RECENTLY ADDED FEATURE
We have added an optional W-Terminal or TACH pickup wire to this alternator. This option is only available on these “SE” Denso / dodge alternators that eliminate the PCM. When you select this option we will provide a tach lead for connection to a diesel specific aftermarket tach. This is only available at the time of assembly and older units are not physically eligible for retrofit.
The connection is simple, the wire is provided by us but does not need to be used if no tach is intended.
This will not work with factory equipped tachometers or ignition based tachometers, only a stator signal tachometer. (tach shown is not included)

Cummins 1 wire alternator
Best way to go if you have had trouble with your external voltage regulator in the past. Simple as can be to install with holes exactly where factory alternator goes and correct pulley. Little pricey but think of the long run. Charges great. Great product
